EMBOSSING DEVICE.

To all whom it may concern Be it known that I, VERNON E. BAKER, a citizen ofthe United States, and a resident of the city. of Elyria, in the county of Lorain and State of Ohio, have invented a new and useful Improvement in Embossing Devices, of which the following is a full, clear, and exact description.

My invention relates to improvements in embossing devices and it consists in the combinations, constructions and arrangements, herein described and claimed.

An object of my invention is to provide an embossing device that embosses a thin strip of metal during part of its operation and automatically feeds another portion of the strip to be embossed during another part of its operation.

A further object of-my invention is to provide a device of the type described that embosses and cuts off a portion of a strip of metal during part of its operation and automatically feeds another portion of the strip to be likewise embossed and cut during another part of its operation.

A further object of my invention is to provide a device of the type described that is simple in construction, eflicient in operation, and thoroughly practical commercially.

Other objects and advantages will appear in the specification and the novel features of the invention will be particularly pointed out in the appended claims.

- My invention is illustrated in the accompanying drawings, forming part of this application in wh1ch Figure 1 is a side elevation of the device,

Fig. 2 is a side elevation of the device partly in section,

Fig. 3 is a section on the line 33 of Fig. 2,

Fig. 4 is an enlarged portion of the device,

Fig. 5 is an enlarged portion of the device shown in section.

In carrying out my invention 1 provide a base 1 which is secured to a table or the like by screws 2. A support 3 having a diskshaped head 4, is integral with the base 1. From the center of the support 3 and extending to the middle of the disk-shaped head 4, is a slot 5 which is adapted to receive a handle 6'pivotally mounted upon a pin 7, that is carried by the disk-shaped head 4 (see Fig. 2).

A horizontal bore 8 extends transversely through the disk-shaped head 4. On each side of the head 9 of the handle 6 are slid- Specification of Letters Patent.

ably disposed in the bore 8, two disks 10 and 11 which have their outer faces flush with the sides of the disk-shaped head 4 (see Fig. 3).- Each of the disks 10 and 11 has a recess on its inner surface which extends in from the periphery as designated at 17' and 18. Adjacent the outer faces of the two disks 10 and 11' are another pair of disks 12 and 13 that are bigger in diameter than the diameter of the bore 8. and thus bear against the sides of the disk-shaped head 4. The pin 7, which pivotally carries the handle 6, extends through the alined centrally located bores in the disks 12, 10, 11, and 13, and has a threaded. opening extending inwardly a short way from each end in which two screws 14 and 15 are disposed. It will thus be seen that there can be no lat eral movement of the moving parts when they are rotated by the handle 6.

Depending from the disk-shaped head 4 is a cylindrical shaped member 16 which has extending inwardly from the bottom a vertical bore 17 (see Fig. 2). Connecting the bore 17, with the bore 8 is a bore 18 which is much larger in diameter than the bore 17, thus forming a shoulder 19 at the junction of the two bores 17 and 18.

A plunger 20 having a diameter which is the same as the diameter of the bore 17 is spring 21. It will thus be seen that a movement of the handle 6 will raise or lower the plunger 20.

Secured to the bottom of the plunger 20 in any suitable manner is a die carrying member 24. Another die carrying member 25 integral with the base 1 is positioned directly beneath the die carrying member 24. A plurality of male dies 26 are held in place by a set-screw 27 in the member 24 while a set-screw 29 holds a plurality of female dies 28 in position in the member 25. With this construction it is obvious that the dies can easily be changed and thus new printing matter obtained from the same machine.

The member 24 has on its forward Binderside a cutting edge 30 which is adapted to register with a groove 31 that is on the top of the member 25 (see'Fig. 2).

A reel 32 comprising two spaced apart discs 33 is mounted on a pair of arms 34 which are integral with the base 1. The two arms 34 have projecting lugs 35 positioned between the base 1 and the reel 32 which pivotally carry a pair of horizontally disposed contacting rollers 36 and 37. Carried by the roller 37 is a ratchet toothed gear 38 which engages ratchet teeth on a rod 39 pivoted on the rotatable disc 13. The ratchet teeth on the rod 39 engage and rotate the ratchet toothed gear 38. only when the handle 6 is swung up, which movement carries the rod 39 in a downward direction. A thin pliable metal strip 40 is wound around the reel 32 and its free end is frictionally held between the rollers 36 and 37.

From the foregoing description of the various parts of the device the operation thereof may be readily understood. On the upstroke of the handle 6, which is caused by the compression spring 21 forcing the plunger 20 against the cam surface 23 of the head 9, the disk 13 that pivotally carries the rod 39 rotates, and forces the rod 39 down.

I This movement causes the ratchet teeth in the rod 39 to engage the ratchet toothed gear 38 and to rotate the rollers 36 and 37 a sufficient number of turns to cause a part of the pliable metal strip ,40 to be fed between the die carrying members'24 and 25. The handle 6 is then manually forced down against the tension of the spring 21 and brings the two die carrying members 24 and 25 together which causes the metal 40 to be pressed into the various characters roduced by the registering of the dies and also cuts the metal strip 40 at the cutting edge 30. This same movement causes the rod 39 to move up without engaging the ratchet toothed gear 38 so as to turn it. After the metal has been embossed in the manner described, the first movement again takes place which feeds another section of the metal 40 between the die carrying members 24 and 25, and permits the removement of the piece that has already been embossed and cut.

I claim:

1. An embossing device comprising a base, stationary dies carried thereby, a reciproeating plunger, movable dies carried by said plunger, a handle for operating said plunger, a circular plate rigidly, connected to said handle, a rod provided with ratchet teeth pivotally mounted to said plate between the center and the rim thereof, a
